I have a carrier FC4DNF042 unit and I am have trouble with the fan motor. It moves very slow then stops after a few seconds then does it again over and over. It doesn't move fast enough to move any air flow through the vents. It is run by a GE ECM motor X13 1/2 HP 230VAC. I get 230 Volts at the motor and it does turn but nowhere near where it should be. I am completely stumped on the problem and have no idea where I can get a replacement motor either if that is even the problem. Any info would greatly appreciated!!

Any info would> greatly appreciated!!The X13 motor is a DC motor and does not use a capacitor. There is a special tool to test and determine if the motor itself is defective or the inverter. Only HVAC techs will have this testing tool and once the problem has been determined usually only HVAC techs will have access to purchasing the parts. I can't vouch for what available over the internet.
